##### 1 Answer

#### Answer

#### Answer:

#### Explanation

#### Explanation:

#### Answer:

The principle of conservation of momentum, both linear (also known as translational) and angular, is a universal principle of Physics.

#### Explanation:

Angular momentum,

Take the time derivative of that

We give the term "torque" to

We give

Expanding that last equation with the variable names

The equation

If there are no external torques acting on a body,

Therefore

Therefore, we have **Conservation of Angular Momentum** .

I hope this helps,
